Ball valves in the primary circuit
n
Piston valves in the secondary circuit
n
Safety valve in the secondary circuit
n
Pre-installed controller
n
Temperature probe on the cold water supply
n
Temperature probe on the heating supply
n
Ultrasonic flow rate meter on the domestic hot
water outlet
n
Primary pump that can be shut off
n
Ball valve for filling/drainage, for bleeding the
